Pyloric hypertrophy and gastric outflow obstruction in an adult ornate bichir (Polypterus ornatipinnis)

open access: yesVeterinary Record Case Reports, Volume 13, Issue 1, March 2025.
Abstract A 5‐year‐old, captive bred, 327 g female ornate bichir (Polypterus ornatipinnis) presented with a history of reduced appetite and cranial coelomic swelling. On physical examination, the swelling was smooth, soft, devoid of masses and consistent with an enlarged stomach. No other abnormalities were detected.

Ecological structure and function in a restored versus natural salt marsh. [PDF]

open access: yesPLoS ONE, 2017
Habitat reconstruction is commonly employed to restore degraded estuarine habitats and lost ecological functions. In this study, we use a combination of stable isotope analyses and macrofauna community analysis to compare the ecological structure and ...

Impact of Commercial Probiotics on Growth, Prophenoloxidase, Superoxide Dismutase, and Digestive Enzyme Activity in Macrobrachium rosenbergii Cultured at Different Stocking Densities

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
An experiment using a 4 × 3 factorial design was conducted to evaluate the impact of three commercial probiotics and a control (no probiotic treatment) on the growth, digestive, and immune enzymatic indices of prawns (Macrobrachium rosenbergii) at three stocking densities (2, 4, and 6 m−2).

The implications of temperature-mediated plasticity in larval instar number for development within a marine invertebrate, the shrimp Palaemonetes varians. [PDF]

open access: yesPLoS ONE, 2013
Variations in larval instar number are common among arthropods. Here, we assess the implications of temperature-mediated variations in larval instar number for larval development time, larval growth rates, and juvenile dry weight within the palaemonid ...

Sensitive biomarker responses of the shrimp Palaemonetes argentinus exposed to chlorpyrifos at environmental concentrations: Roles of alpha-tocopherol and metallothioneins.

open access: yesAquatic Toxicology, 2016
The aim of this study was to evaluate the toxic effects of chlorpyrifos (CPF) at environmental concentrations on the shrimp Palaemonetes argentinus, a South American native species. Organisms were exposed to environmentally relevant concentrations of CPF

Can consumers avoid mislabelling? Genetic species identification provides recommendations for shrimp/prawn products

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 15, Page 9486-9493, December 2024.
Abstract BACKGROUND Crustaceans of the superfamily Penaeoidea (e.g., shrimps and prawns) are among the most commercially available aquatic products worldwide. However, there are few studies regarding not only the presence but also the characteristics of mislabelling in these food products.

Effects of water quality on fish parasite biodiversity and physiological responses in the host fish Clarias gariepinus from a eutrophic lake subjected to acid mine drainage in South Africa

open access: yesIntegrated Environmental Assessment and Management, Volume 20, Issue 5, Page 1539-1553, September 2024.
Abstract Elevated concentrations of contaminants have negative impacts on aquatic organisms and their parasites. Changes in parasite infections have been proposed as a technique for monitoring the health of aquatic ecosystems. Furthermore, alterations in physiological responses (biomarkers) of organisms have also been used to delineate ecosystem ...
